[Lab news] Sand lance spawning

For the last 6 weeks, we housed about 100 adult sand lance (Ammodytes dubius) in our lab that Chris and Jake brought from a research cruise on Stellwagen Bank (Massachusetts Bay). We watched them visibly ripen in our tanks, and today managed to strip-spawn 10 males and 10 females, obtaining several thousands of eggs and having them develop under different CO2 conditions now.
Thumbs up, and fingers crossed for the next steps!
